The third variety for sweet potato that we introduce into our garden since we started growing this sweet tuber is sweet potato with purple skin and white flesh. I wanted to grow sweet potato with purple skin and flesh, thinking of Malaysian traditional cake when I harvested the tubers later. However, I bought wrong tubers from the market without checking the inner flesh colour. Usually I prefer to grow them from young shoots from sweet potato plants left growing over-winter in our garden. But with new variety into the garden, we have to get the new plants from tubers. When spring came, I simply just push half of the purple sweet potato tubers into the soil in container that were growing beet roots. I did forgot those tubers for a while left in the container. Snail/Slugs even munched on the sweet potato as seen in the photo. After young shoots sprouted from the sweet potato tuber eyes were big enough to cut and able to produce some root, I transplanted them in containers.
It was easier to differentiate the sweet potato variety we grow this time. Because for this new member in the garden that we are growing have dark purple veins when the other 2 have green veins with different shape of leaves.
Sweet potato grows very well in container. I was a bit mischievous when I had extra purple sweet potato shoots ready to plant in hand that I planted one in a container that were growing leek and parsnips. I thought that I would not get many sweet potato harvest from that container since it was only intended sweet potato foliage to cover the soil like mulch. I was really surprise that among 4 containers that we grow purple sweet potatoes, the ones that were grown along with parsnip and leeks gave the biggest and most tubers compared to other containers. The parsnip roots were also remarkably decent size of parsnip root harvest. Lemon basil and sweet potato also seems to get along well together.
Some of the purple sweet potatoes tubers harvested from our container garden.
Here are the debris of the purple sweet potato plants pull out from the containers by my husband. If you live in a frost-free area you can simply plant it back somewhere else in full sun. I have experimented with one plant last year after I harvested all the tubers and planted somewhere else in full sun. That plant still live at our backyard for more than a year now thriving without any tender loving care. We have not harvested that plant simply because we don't have the time and we still have many sweet potatoes plants sprouting from compost and growing as they please. Sweet potatoes has somehow become weeds in our garden. I won't be surprised when spring comes we got several sprouted sweet potato shoots somewhere in the garden.
Because I have many small containers at the moment, I selected some good-looking young shoots from the debris that have many strong roots attached and planted them in containers. I left them outdoors, any plants of ours will be train to be hardy plants which is tolerant of the weather we have in winter and extreme summer heat here.
If these cuttings do well, I plan to give it away at veggie swap or seed-saver meetings.
I have received so many valuable advice and treasures from this community.
Sweet potato is one of the easiest edible plant to grow if you have suitable climate for growing this easy-going plant. Grows very well in pots like potato, not impossible even for gardeners with small space. I have a capsicum plant growing together with a sweet potato in container and the capsicum plants give a lot of produce as usual. Although, I have not yet harvest the sweet potato tubers, so I can't comment on the sweet potato harvest. A lemon basil plant was also growing together in the same pot during summer. If you can't wait for the harvest, you can snip some young shoots to enjoy while waiting for tubers.
