Ar fore braf o wanwyn, roedd marchnad Caerdydd yn llawn bywyd.

On a fine spring morning, the Caerdydd market was full of life.

Roedd aroglau ffres y ffrwythau a'r llysiau'n cymysgu gyda'r persawr hyfryd o flodau lliwgar.

The fresh scents of fruits and vegetables mixed with the delightful aroma of colorful flowers.

Ar hyd yr eiliau, roedden nhw i gyd yn brysur - gwerthwyr, cwsmeriaid, a Rhys, a oedd ar drywydd cynlluniau mawr ar gyfer ei ardd.

Along the aisles, everyone was busy - sellers, customers, and Rhys, who was on the hunt for grand plans for his garden.

Roedd Rhys yn adnabyddus yn ei gymdogaeth am ei hoffter o blanhigion, ond nid oedd dechrau ardd ei swydd gref.

Rhys was well-known in his neighborhood for his love of plants, but starting his garden was no easy task.

Roedd angen iddo greu'r ardd flodau harddaf yn y gymdogaeth ond roedd yn gwybod bod angen helpu arno.

He needed to create the most beautiful flower garden in the neighborhood, but he knew he needed help.

"Rhaid i mi wneud yn siŵr fy mod yn cael y planhigion cywir," meddai wrth ei hun.

"I must make sure I get the right plants," he said to himself.

Gyda hynny, cyfarfu Rhys â'i ffrind da, Carys, yn y farchnad.

With that, Rhys met his good friend, Carys, at the market.

Roedd Carys yn gwybod llawer am blanhigion.

Carys knew a lot about plants.

Roedd hi, fodd bynnag, yn amheus o'r cynlluniau rhy fawr a grand Rhys.

However, she was skeptical of Rhys's overly grand plans.

"Mae'n rhaid i chi wybod pa blanhigion fydd yn tyfu'n dda yn eich gardd," meddai Carys, gan wenu.

"You need to know which plants will grow well in your garden," said Carys, smiling.

Yn yr eil nesaf, roedd stondin Eleri, a oedd yn rhedeg siop arddio.

In the next aisle, there was Eleri's stall, who ran a gardening shop.

"Bore da, Rhys! Pa gynlluniau sydd gennych heddiw?" gofynnodd Eleri, ei llygaid yn llawn cymhelliant.

"Good morning, Rhys! What plans do you have today?" asked Eleri, her eyes full of enthusiasm.

"Rwyf am greu ardd a fydd yn gwneud i'm cymdogion genfigennu," cyfaddefodd Rhys, yn dynn ar ei fag siopa.

"I want to create a garden that will make my neighbors envious," admitted Rhys, clutching his shopping bag tightly.

Roedd Eleri'n gwrando'n astud wrth iddo grybwyll coed prin o liwiau bywiog.

Eleri listened intently as he mentioned rare trees of vibrant colors.

"Mae'n well cael rhywbeth sy'n gallu goroesi tywydd Cymru," awgrymodd Eleri, ei llais yn garedig ond penderfynol.

"It's better to have something that can survive Cymru's weather," suggested Eleri, her voice kind yet firm.

Rhys edrychodd ar y blodyn prin - roedd o'n las fel yr awyr, ond roedd yn gofyn gofal llawn.

Rhys looked at the rare flower—it was blue like the sky, but it required full care.

Yna edrychodd ar blanhigion addfwynach, rhai yn fwy galluog i dygymod â thir a thywydd ei ardd.

Then he looked at more manageable plants, ones more capable of coping with the soil and weather of his garden.

Roedd yn gwybod y byddai'n wylltio Carys ac Eleri pe bai'n dewis rhywbeth na fyddai'n para.

He knew that he would upset Carys and Eleri if he chose something that wouldn't last.

Roedd angen iddo wneud penderfyniad, ac yn sydyn daeth yr ateb.

He needed to make a decision, and suddenly the answer came.

Edrychodd ar Carys ac Eleri, gan sylweddoli mai dyma oedd ei gyfle i ddysgu gan arbenigwyr o'i gwmpas.

He looked at Carys and Eleri, realizing that this was his opportunity to learn from the experts around him.

"Byddaf yn mynd gyda'r planhigion ymarferol," penderfynodd, calon falch o'i gytgord newydd.

"I will go with the practical plants," he decided, heart full of new understanding.

Wrth adael y farchnad, roedd Rhys yn teimlo bod ei fwriad wedi newid.

As Rhys left the market, he felt that his intention had changed.

Doedd dim angen iddo fynd ar ei ben ei hun, a gwerthfawrogodd gymorth ei ffrindiau.

He no longer needed to go it alone, and he appreciated the support of his friends.

Roedd pob planhigyn a brynodd, ar y cyfan, yn atgoffa ef o gyflawniad mwy, un sy'n sôn am gydweithio a bod yn realistig.

Every plant he bought, in essence, reminded him of a greater achievement, one that speaks of collaboration and being realistic.

Rwan, wrth i'r ddiwrnod droi'n nos, roedd Rhys wedi dysgu gwersau gwerthfawr.

Now, as the day turned to night, Rhys had learned valuable lessons.

Roedd yn falch gyda'i ddewis - ei ardd newydd fyddai un i'w chofio; nid yn unig oherwydd ei harddwch ond am y llawenydd a'r bywiogrwydd a ddaeth o weithio gyda'i gilydd fel tîm.

He was pleased with his choice—his new garden would be one to remember; not only for its beauty but for the joy and vibrancy that came from working together as a team.

Mae'n dysgu hefyd am bŵer cyngor cyfeillion, sy'n cael eu gwerthfawrogi am byth.

He also learned about the power of friends' advice, which would be treasured forever.
