Gardeners' Notes:

This exceptionally beautiful climber is non-aggressive and more easily managed than most tropical vines. It can be grown as a shrub.

It can set buds multiple times on each inflorescence. Shortly after the corollas (flowers) are shed, cut all the pedicels (and I know this can be tedious) without cutting any woody stems. About two weeks later you'll see a second cycle of bloom. And after those corollas are shed, you can cut the new pedicels for a third round of bloom, if you have the patience.

Flowers open deep lavender-violet and gradually fade to white over about a week before dropping. They may be called mauve, but not rose.

The garlic scent is only released if the leaves are rubbed or crushed. Otherwise the plant is... read more

This woody climber is growing in my house for 20+years. The climate of Jaipur ( Rajasthan , India ) is semi arid. Summer temperature ranges between 40 to 46 Celsius (high end) and winter low is 5 to 9 degrees ( centigrade or Celsius ). Rain fall is not very high , average about 26-28 inches.
This climber in my place has grown to a height of 25 feet + . It could have attained more height , but I get it pruned yearly. And it needs support to climb.
It flowers very profusely two-three times a year. Some pods are formed may be Seeds are also formed , which I could not collect.
Will post some photographs here

I have two of these flanking a pink bower vine. Easily a favorite, love the perfect bouquets of purple fading to lilac flowers, very nonaggressive plant. Although the single bower vine easily overcomes the two garlic vines when unchecked, they are
stunning in bloom
together. Tiny birds ( I
have seen painted
buntings and ruby
throated hummingbirds
and several other
species shelter there,
especially during rain)
love it too.

My two garlic vines have been growing for several years in the strong Miami,Florida sun. One has never bloomed, the other one has grown taller and blooms twice a year in Dec and Jan. The blooms last only two weeks. Aye, there's the rub, it doesnt bloom enough for my taste, otherwise it's a joy. It's not invasive. It is not destructive of fences or trellises, it's a gentle vine.
Home Depot recommended acid fertilizer.

Pretty trumpet shaped flowers that start out bright medium purple, and fade to pale lavender as they age, giving the overall look of the vine a tricolor look when loaded with lots of blooms.

The foliage when rubbed or brushed against, gives off the fragrance of garlic, hense the name.

The blooms have some fragrance, but it is very mild.

This is not commonly found in commerce yet, and is on the tender loves the heat. Mine sits and pouts until mid-summer when it is the hottest.

The blooms can last almost a week...

They root from stiff green cuttings and require heat to root. Same with the seeds. The seeds do not need a cold spell, and should be surface sown with heat.
