Know before you buy
Yes, because these vines grow 5–6 feet tall, they require support to thrive. Plan to plant them near a trellis, fence, or garden arch so the vines have something to climb as they mature.
Absolutely. These heirloom flowers are pollinator-friendly and specifically known to attract bees, butterflies, and hummingbirds to your garden.
While they are best suited for in-ground planting due to their height and climbing nature, you can grow them in large containers if you provide a sturdy trellis and ensure the pot is deep enough to support their root system.
Sweet peas prefer cooler weather and should be planted in the spring. Aim for a soil temperature of around 60 degrees Fahrenheit to ensure the best germination results.
You can expect germination to occur within 10 to 21 days after planting. Ensure they are planted at a depth of 1 inch for optimal growth.
No, these are annuals, meaning they complete their entire lifecycle within one growing season. You will need to replant seeds each spring to enjoy them again.
