Looking for a hosta that can take the heat? While some varieties aren’t heat resistant, there are others that can be grown in hot places like Tuscon, Houston, and Orlando. Let’s look at some of the best hostas for the warm climate of Zone 9! We’ll also chat about some planting and care tips that are vital in hotter zones.
Growing hostas in Zone 9
Growing hostas in USDA Zone 9 can be a bit challenging, as these plants typically prefer cooler temperatures. However, with the right care and conditions, you can successfully cultivate these shade-loving perennials in warmer climates.
The key is selecting the right varieties. Some hostas are more heat tolerant than others. Look for heat-tolerant cultivars or those with thick, glossy leaves, as they are generally more resilient to the heat.
Anecdotally, I find that yellow varieties do better in sunny areas than those with blue leaves (in general). I wonder if the lighter leaf color helps the plant stay cooler in the sun. If you’ve got your heart set on a blue variety, options like ‘Halcyon’ and ‘Blue Angel’ are known for retaining their blue color better in warmer conditions. The following sections of this article list some of the best varieties of hosta to grow in hot climates.
In warm climates, providing water is absolutely vital. You’ll need to water frequently when the hosta is first planted, keeping the soil moist whenever possible for the first six weeks after planting. Continue watering often until the hosta has been in the ground for a couple of years and has established a big root system. Drip irrigation works well for watering hostas.
Planting location is crucial—hostas in Zone 9 need protection from the intense sun. Choose a spot that offers partial to full shade, ideally receiving morning sun and afternoon shade. This helps prevent the leaves from scorching and fading, especially for blue-leaved varieties whose color can diminish with too much sunlight.
In addition to proper shading, soil, and water management are vital for growing hostas in Zone 9. These plants thrive in rich, well-draining soil, so amend the soil with organic matter to improve its structure and nutrient content.
1. June hosta
‘June’ hosta is a medium-sized variegated hosta variety. This plant is heat tolerant and does well in zone 9 climates. The foliage is a beautiful mix of green, blue, and yellow. The flowers are quite pretty and bloom in mid to late summer.
I really like the variegated leaves of June hosta. It’s just as pretty in a cut flower arrangement as it is bringing a bit of brightness to a shady corner of the garden. This one is a favorite for a reason.
2. Sum & Substance hosta
‘Sum & Substance’ is a large hosta variety that can grow up to 3 feet tall. This plant has light lime-green leaves and can be grown in zone 9 as long as it receives shade (especially in the afternoon). The flowers are white and bloom in mid to late summer.
3. So Sweet hosta
‘So Sweet’ hosta is a small variety that only grows to about 8 inches tall. This plant has heart-shaped leaves that are dark green with white margins. It’s quite heat tolerant and does well in zone 9.

‘Patriot’ is a very popular hosta variety that is medium-sized and can grow up to 2 feet tall. The leaves are dark green with white margins. This plant does well in zone 9 climates as long as it receives afternoon shade. The flowers are light lavender and bloom in mid-summer.
5. Key Lime Pie hosta
‘Key Lime Pie’ is a pretty variegated hosta with dark green leaf centers and ruffled yellow margins. These plants are heat resistant and can be grown in zone 9 (but do give them shade). As an aside, hostas with the word “pie” in their name often have ruffled or corrugated “pie-crust” edges to their leaves (including this one).
