Foundation Plant That Can Take Extreme Heat

Filed Under: Landscape Gardens · Keywords: foundation plant, extreme heat, hot · 1775 Views
My mom needs a foundation plant that can take extreme heat. The front of her house gets noon to afternoon sun. Anything we have planted thus far has practically baked to a crisp because of the heat that radiates from the house. The space is small - about a 2 x 5 foot long bed. A nice bush or some kind of flower would be nice. We tried petunias, but now they are crunchy!!
Thanks so much!!

Answer #1 · Maple Tree's Answer · Melissa-I have listed a few shrubs I have grown for years at several homes. I am in Zone 10a. These shrubs receive full sun along with the added heat from reflected sunlight. These shrubs have granite stone or white stucco walls behind them. They take the heat exstremely well with average to low water needs once established. I also listed a few flowering plants I use in my warmest gardens that get all day sun. My favorite flower is the dianthus. They started blooming in early Spring. When the flowering slows I prune the plants back and in a few weeks they are in full bloom again. Many summers I will get 3 periods of blooming before fall.

You can copy the plant names below and paste them in the search box under the 'Plants' tab above. This will take you to their respective plant files that will have a picture and the plants characteristics noted.

Perennial shrubs:

Snow Pink Indian Hawthorne - (Raphiolepis indica 'Snow Pink')

Wheeler's Dwarf Pittosporum - (Pittosporum tobira 'Wheelers Dwarf')

Firestorm Nandina - (Nandina domestica 'Firestorm')

Moonbay Nandina - (Nandina domestica 'Moon Bay')

Purple Pixie Loropetalum - (Loropetalum chinense 'Purple Pixie')

Peter Pan Agapanthus - (Agapanthus africanus 'Peter Pan Blue')

Some flowering plants I use for spring and summer color that take full sun.


African Daisy

Yellow Marguerite Daisy

Deep Plum Angelonia - (Angelonia angustifolia 'Deep Plum'

Aztec Purple Verbena - (Verbena 'Aztec Purple')

Hope this helps.

Melissa-Some times your soil may help in allowing the plants to dry out. If it is a heavy clay it may not have been absorbing the moisture the plant needs. Dry clay soils become hard allowing water to run off and not soak in. Make sure your soil is well draining, doesn't stay to dry or too wet. You can mix compost or other soil amendments, 50/50 mix, to help with the draining and moisture retention. A layer of mulch around the plant will help to keep the soil cooler and moist in the warmer months and help protect the plant from freezing in the winter.
You can also have fun finding other plants that might work for you by using the plant search tool under the 'Plants' tab above. Go to the second option and there you can search for plants with the characteristics you would like. You can search by entering your hardiness zone, size, foliage-flower color, type of plant, soil type, sun exposure, etc.. You may find other plants you would like to see when you visit the nursery.
Please let me know how you make out.
