Seedlings: ‘Lemon Swirl’ Four O’Clock, Mirabilis jalapa

The Four O’Clock is best described by Pomona Belvedere. Customer feedback was that the plants are not bushy as often described but sprawling as Ms. Belvedere writes. However, profuse blooms and toughness should be enough for anyone. Try digging up the bulb at the end of the season in NC if you want to have a vigorous start to the next year.

Germination: As pictured above. Seed was room-temperature stored and purchased in February 2014 making the seed over 2 years old. Seed covered in soil to 3/8 inch and germinated at room temperature with light which provided heat, though the light itself was unimportant. Germination was 50% at 5 days and 90% at 9 days.

Seedlings: African Foxglove, Ceratotheca triloba

The african foxglove is a plant I’d recommend every NC gardener try at least once. My sole complaint is that the blooms do not show up in mass, instead you get one or two fully open along each spray and as the next opens the current die back. In mass plantings perhaps this is overcome. If you are looking for a breeding project, this is a plant that needs a single improvement to take off.

Germination: As pictured above. Seed was room-temperature stored and purchased in February 2014 making the seed over 2 years old. Seed was covered in soil proportional to seed size and germinated at room temperature with light. Germination was 10% at 7 days and 25 days. This seed will be retested with surface sowing to see whether light or age was responsible for the low germination.

Seedlings: Purple Passion Flower, Passiflora incarnata

The purple passion flower is an interesting germination challenge that I haven’t quite solved. But below you can see what this large vine starts out as. It does produce large flowers with alien beauty. Flowers and fruit usually take a couple years to get going. Fruit is edible, but not the same as the passion fruit so commonly used on British cooking shows which is Passiflora edulis. The vine is vigorous and doesn’t stay put. Be careful where you plant it.

Germination: As pictured above. Seed was room-temperature stored and purchased in March 2016 making the seed less than 6 months old. Seed was pre-soaked in a solution for 24 hours, rinsed, and then covered in soil to 1/4 inch and germinated at room temperature with light which provided heat, though the light itself was unimportant. Germination was 27% at 9 days and 40% at 15 days. I stopped germination after 30 days. Remaining seeds were still hard.

Seedlings: Orange Jalapeno Pepper, Capsicum annuum

The Orange Jalapeno Pepper, Capsicum annuum, is very productive pepper that consistently gets positive feedback. Though I don’t often mention my seed suppliers, this variety was from JL Hudson in California. JL Hudson, Seedsman is a public access seed bank. While not as easy to use as a commercial seed seller, he provides great seeds, great research, and respects your privacy. If you like what he sells, but just want plants – order from Fresh From Seed.

Germination: As pictured above. Seed was room-temperature stored and purchased in February 2014 making the seed over 2 years old. Seed covered in soil to 1/4 inch and germinated at room temperature with light which provided heat, though the light itself was unimportant. Germination was 40% at 12 days and 75% at 16 days.

Peppers take longer to germinate than tomatoes, for example, but tend to come up over a few days once they get going. I’ve often seen stragglers turn up weeks later, however. If you are germinating valuable pepper seed, it makes sense to hold on to the pot for a few weeks beyond the initial germination period.

Seedlings: Moon Vine, Calonyction aculeatum

Moon Vine, Calonyction aculeatum, is a fast-growing, aggressive vine with large white flowers opening in the evening. It produces profuse seed but luckily does not self sow in central NC allowing for control of this vine in your garden. Even before the flowers open they are wildly attractive with a fluted, spiral shape. It’s recently been re-classified as Ipomoea alba. You may recall morning glories, sweet potatoes, and bindweed as being in this genus.

As you can see from the photo below, the large leaves are tightly wound up inside the seed and I’ve found that they don’t unfurl and expand without some help or without some tearing. The true leaves came in a few days later and looked normal.

Germination: As pictured above. Seed was room-temperature stored and purchased in March 2016 making the seed less than 6 months old. Seed was cut with a utility knife on the pointed end and covered in soil to 1/2 inch and germinated at room temperature with light, though the light was unimportant. Germination was 50% at 6 days and 100% at 8 days.

I have germinated seed harvested in 2011 in 2016, making the seed 5 years old. Seed was room-temperature stored. I don’t recommend boiling seed, it helps but it’s inconsistent compared to mechanical scarification (cutting). If you don’t treat the seed, be prepared to wait months or years for germination.

Order moon vine.

Seedlings: Chervil, Anthriscus cerefolium

Chervil, Anthriscus cerefolium, is a pretty little herb. NC-based growers should try it in part-sun to sun during spring and fall. It’s a good candidate for late fall trials. Towards late spring and summer I recommend cool afternoon shade or waiting. Could easily be grown in a windowsill. If you use parsley, try chervil. The finely divided leaves are attractive and the taste is light with no bitter end.

Germination: As pictured above. Seed was room-temperature stored and purchased in August 2012 making the seed over 3.5 years old. Seed covered in soil to 1/4 inch and germinated at room temperature with only incidental light. Germination was 25% at 7 days and 73% at 11 days.
