Introduction to the blue angel hosta
The blue angel hosta is a popular variety of hosta plant that is known for its large blue leaves. It is a hardy perennial that can thrive in a wide variety of climates, making it a popular choice for gardeners. The blue angel hosta grows best in partial shade and moist soil and is also tolerant of hot temperatures.
Blue angel is one of the largest blue-leaved hostas. Established plants can reach 5-6 feet wide and up to 3 feet high. The flowers are a very pale lavender color on tall, 4-foot high stalks in midsummer.
Like most hostas, this classic hosta grows best in sandy loam soil. These plants can also grow well in clay soil but often take longer to grow to full size. Hostas prefer slightly acidic soil.
The blue angel hosta was bred by Florence Shaw of Weston, Massachusetts. The parentage of the variety is unknown, as hybridizing records were lost. That said, it likely includes famous early giant hostas like ‘Goliath’ and ‘Elatior’ in its parentage. Florence Shaw was also the breeder of many other famous large hostas including ‘Sum & Substance’, and ‘Sun Power’ (all of which were introduced into the American Hosta Society by Paul Aden).

Where to plant blue angel hosta
Blue angel hosta thrives in a wide variety of climates: zones 3-9. They should be planted in an area that receives partial or full shade. Hostas grow best in well-drained sandy soil.
Blue angel hostas are not the most sun-tolerant variety and should be planted in a partial shade area. Shade in the afternoon is a must in any climate with a harsh, hot, afternoon sun. These hostas can be grown in partial sun in mild climates but will require quite a bit more water to thrive.
Hosta plants grow well in sandy loam soil that allows excess water to drain out freely. Avoid planting them in low spots where water pools after rainfall. While they do thrive in sandy loam, blue angel hostas are tolerant of clay soil. These large hostas will grow more slowly in dense soil, but may not require feeding with fertilizer as often.
In terms of pH level, hostas grow best in slightly acidic soil. Do a soil test to learn the natural acidity of your soil. Hostas grow best in soil with a pH level of 6 (or close to it). Alkaline soil can be amended with an organic soil acidifier prior to planting and in the spring/fall to bring the acidity of the soil closer to optimal levels.
When to plant blue angel hosta
The best time to plant blue angel hostas is in the spring after the last frost has passed. You can also plant them in the fall, although they may not have as much time to establish themselves before winter.
How to plant blue angel hosta
Planting blue angel hosta is similar to planting most other perennials. Start by preparing the soil where you will plant the blue angel hosta. Loosen the soil to a depth of 12 inches. Add organic matter to the soil, such as compost or manure, and mix it in well.
Next, dig a hole that is twice as wide as the blue angel hosta’s root ball. Gently remove the plant from its container and set it in the hole. Fill in the hole with soil, being careful not to bury the blue angel hosta’s crown (the point where the roots meet the stem). Water the blue angel hosta well and mulch around the plant to help retain moisture.
How to care for blue angel hosta
Blue angel hostas are relatively low-maintenance once established. They need to be watered regularly, especially during hot, dry weather. In nutrient-poor soils, they can be fertilized in the springtime.
Watering requirements for blue angel hosta
Blue angel hosta is a low-maintenance plant but needs to be watered regularly at first, especially during hot, dry weather. The best way to water them is right at soil level. Use a watering wand or a drip irrigation system to water the roots without getting the leaves wet. Apply a thick layer of mulch around the blue angel hosta to help retain moisture in the soil. Established hostas are quite drought-tolerant.
Fertilizing blue angel hosta
Fertilize blue angel hostas in the spring with a slow-release fertilizer or compost. These plants do not need a lot of fertilizer, so be careful not to overdo it. Most fertilizers are granular or powdered slow-release organic products that are easy to sprinkle on the soil surface and water into the ground.
Pruning blue angel hosta
First, make sure to clean up the plant early in the spring before new growth begins. Prune any dead or damaged leaves and stems left over from winter. Be careful not to damage the plant’s roots when pruning.
Pruning is minimal during the season. Just remove any yellowed, unsightly leaves if they are bothering you. However, blue angel hostas are pretty tolerant to just being left alone.
Late in the season, blue angel hostas will start to produce flowers on tall stalks. You can prune these off if you don’t want them, or let them be for some extra winter interest. Just be sure to remove the dead flower heads in spring if you do leave them up over winter.
Cut back the entire hosta plant to the ground in the fall after the first hard frost. Remove the stems and leaves and compost them so they do not create a habitat for slugs and other pests right at the crown of the plant.
Plant care tips for blue angel hosta
Weed the soil around the base of the blue angel hosta for the first few years as the plant grows and becomes established. This will lessen competition from weeds and allow the blue angel hosta to thrive. A good organic mulch like compost, hardwood mulch, or pine needles will also help keep weeds down.
Companion plants for blue angel hosta
Ferns, impatiens, and begonias are all great companion plants for blue angel hosta. They all thrive in similar conditions, and they also look great together in a garden bed.

If you notice any of these symptoms, you should remove the affected leaves and dispose of them. You can also spray the plant with a fungicide to prevent the disease from spreading.
Bacterial leaf spots are caused by bacteria that enter the plant through wounds in the leaves. The bacteria cause lesions (spots) on the leaves. This can cause the leaves to become discolored and mottled. The leaves may also start to fall off the plant. If you notice any of these symptoms, you should remove the affected leaves and dispose of them. You can also spray the plant with a bactericide to prevent the disease from spreading.
Viral diseases are caused by viruses that infect the blue angel hosta plant. These diseases can be difficult to control because there is no cure for them. The best way to prevent viral diseases is to avoid introducing them into your garden in the first place. You should only buy blue angel hosta from reputable nurseries and garden centers. You should also avoid sharing tools and equipment with other gardeners who may have virus-infected plants.
