Are there any underground plants?
Growing anything other than roots underground is rare, but examples can be found across the plant kingdom. South-central Africa is home to an “underground forest” where many plants flower aboveground but grow woody material below; a Bornean pitcher plant buries its traps under the soil (SN: 7/8/22). Every plant grows in the ground. Roots grow in the soil and green, leafy parts of plants grow above the soil. Depending on what part of the plant we eat, it may be the part of the plant that grows underground. Carrots, for example, are a root vegetable.
What seeds can be planted directly in the ground?
Some of the best vegetable seeds to direct sow include corn; leafy greens, like lettuce; peas; beans; root vegetables, like carrots and radishes; squash; and cucumbers. Most annual flower seeds do well with direct sowing. Popular choices include sunflowers, zinnias, poppies and marigolds. Direct seeding involves planting seeds directly in the soil, while indirect seeding involves first planting seeds in containers like pots before transplanting the seedlings to the soil. Some key advantages of direct seeding are that it requires less labor and results in earlier maturity compared to transplanted crops.Answer: some examples for indirect seeding are snapdragons, nasturtiums, spinach, beets, carrots, and peas.
