Need a vine for a trellis, pole, or fence? Cardinal climber makes a nice partner with scarlet runner bean or morning glory. Deep red flowers with a white/yellow throat attract pollinators and hummingbirds like crazy! We can't say enough about the beautiful, fern-like foliage that together with the flowers make this an eye-catcher! Great container variety. Caution: Most parts of this plant are poisonous if ingested.

This vine was leafy all summer and slow to bloom but the leaves are so beautiful on the trellis I was already decided to put it there again. In the garden bed it grew up a leggy Basye's purple rose and made this beautiful but low producing rose a magnificent support. The vines are strong and long. All of this love all summer over just the wonderful leaves was enough but now, now it is covered in blossoms. They are tiny and yet so clear from a distance in the purest red. This is a new garden staple for me.

many plants are day length sensitive. this does not effect how they grow in many parts of the country, but is most noticeable in Phoenix Arizona. planted when soils are warming in spring the ipomeas in general end up making a nice green screen all summer, but only as the sun moves north and the angle changes with the tilt of the earth will they begin to bloom. late September sees a wonderful flowering for us in Phoenix. As days get shorter in October and November the opening time comes later in the morning. humming birds are just hovering, waiting for the moment! we loose them as soon as we get the frost!

Wonderful Germination

100% germination rate. My dog decided to rip up the first batch, but the second batch is strong. Can't wait for gorgeous blooms and for the hummingbirds to visit.

These seeds germinated quickly. Within a month, the plants were climbing up my grow lights! They grew OK over the summer (zone 3) and the hummingbirds like them, but they do not spread out to cover a fence. If you need coverage, plant closely together.
