Island False Bindweed: A Native California Vine Worth Growing
If you’re looking to add a touch of California’s natural charm to your garden, island false bindweed (Calystegia macrostegia cyclostegia) might just be the perfect native vine for you. This delightful perennial member of the morning glory family brings both beauty and ecological value to native plant gardens across the Golden State.
What Makes Island False Bindweed Special?
Island false bindweed is a true California native, originally hailing from the state’s stunning Channel Islands. As a perennial forb herb, this plant lacks the woody stems of shrubs and trees, instead producing soft, herbaceous growth that dies back seasonally while the root system persists year after year.
Also known by its synonym Convolvulus cyclostegius, this charming vine produces the classic funnel-shaped flowers you’d expect from the morning glory family. The blooms range from pristine white to soft pink, creating a lovely display against the plant’s heart-shaped leaves.
Where Does It Grow?
This native beauty calls California home, where it has adapted to the state’s unique Mediterranean climate and growing conditions.
