Gemiums can be earned through grinding, but grinding is the opposite of fun, and takes too long. If you want to buy 110 gems it's $9.99, which is a lot more expensive than Premium plants, specially when they are on sale. Also gemiums are not shared across profiles while premiums are.

If you say grinding is the better option... Then I have to ask you, how much do you value your time? Even the best gem farming strategies only yield about 10 gems per hour at best. This means it will take you eleven hours to get 110 gems. Which means you value your time at $9.99/11 = $0.91. Is that actually smart? You'll earn more working minimum wage.
